DRIVE-WHEEL.

December 13, 1881.

Application filed October 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, KITTIL ANUNSEN, of Winchester, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Geared Drive- Wheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and 1o use the same, reference being had to the accompanying drawings, which form a part ot' this specification, and in which- Figure l is a side elevation of my improved cogged or geared drive-wheel. Fig. 2 is a t 5 similar view representing the opposite side of the same. Fig. 3 is a diametrica-l section, and Fie. 4 is a perspective detail view, on an enlarged scale, of the device for afxing the sections of theinternally-cogged gear-wheel upon 2o the spokes of the main or drive wheel.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to internal gearwheels which are secured concentrieally-upon the spokes of an outer drive-wheel, such as are used in operating horse-powers, harvesters, and many other classes of machinery, the eX- teror wheel being either in the nature ot`-a pulley or traction-wheel; and it consists in an 3o improved means for securing the inner concentric gear-wheel upon the spokes or radial arms ot' the outer drive-wheel, as hereinafter more fully set forth.

In the annexed drawings, A represents the rim or tread (as the case may be) of the drive or traction wheel, the central hub, B, of which has a double set of alternating radial arms or spokes, represented respectively by the let- Iters G and C. The internal gear-wheel, D, is

4o secured upon lthe inner set of spokes, C, and said gearwheel may either be cast in one piece .or made in sections, which, when united,form

In either case the gearwith a series of equidisthe complete wheel. wheel D is provided tant radial projections, E, coinciding with and corresponding in number to the spokes C. Each of these spurs or projections has a longitudinal groove or recess, a, in its rear side, (see Fig. 4,) which is crossed at right angles by a semicircular recess or depression, b. In placing the gear-wheel upon the spokes@` these will tit into the longitudinal recesses a, and are held in place by bolts c, the eyes d of which are slipped upon the spokes before thesel are screwed into the outer rinn or tread, A, and rest in the sockets or enlargements b, which intersect the grooves or spoke-ricesses a, as hereinbeforedescribed. Theprojectingthreaded ends ot' the bolts c are nutted at e, to bind them against the inner faces of the projections E. In this manner it will be seen that I do not in any manner latter is fixed tirmly in its position, so that it cannot move to either way except with the spokes and wheel A; nor are there any bolts or nuts to interfere with the free and unobstructed meshing of the gear-wheel and its pinions operated by it, as the rim ot' the internal gear projects sufficiently out from the spokes to give free play to the gearing.

'Having thus described myiuveution, I claim and desire to secure by Letters Patent ot' the United States- The combination of' the wheel A, having spokes G l, concentric gear-wheel l), having radial projections E, provided with sockets or recesses a b, and eyebolts c d, nutted ate, substantially as and for the purpose herein shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signatureiu presence ot' two witnesses.
